Whakaoti i te 0.09-0.01(x+2)=-0.02(4-x)

$$0.09-0.01(x+2)=-0.02(4-x)$$

Whakaoti mō x

$$x=5$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -0.01 ki te x+2.

$$0.09-0.01x-0.02=-0.02\left(4-x\right)$$

Tangohia te 0.02 i te 0.09, ka 0.07.

$$0.07-0.01x=-0.02\left(4-x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -0.02 ki te 4-x.

$$0.07-0.01x=-0.08+0.02x$$

Tangohia te 0.02x mai i ngā taha e rua.

$$0.07-0.01x-0.02x=-0.08$$

Pahekotia te -0.01x me -0.02x, ka -0.03x.

$$0.07-0.03x=-0.08$$

Tangohia te 0.07 mai i ngā taha e rua.

$$-0.03x=-0.08-0.07$$

Tangohia te 0.07 i te -0.08, ka -0.15.

$$-0.03x=-0.15$$

Whakawehea ngā taha e rua ki te -0.03.

$$x=\frac{-0.15}{-0.03}$$

Whakarohaina te \frac{-0.15}{-0.03} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{-15}{-3}$$

Whakawehea te -15 ki te -3, kia riro ko 5.

$$x=5$$
